| Title: | CERAMIC GUIDE BLOCK AND METHOD OF MANUFACTURE | ||||||||||||||||||
| Abstract: | A guide block is provided for supporting a blade within a saw, such as a band saw, the guide block being formed from a ceramic material. A ceramic material is provided in powder form initially and is pressed into a billet of compressed ceramic powder. This billet of compressed ceramic powder is machined into a desired shape for the guide block but oversized in all of its dimensions by an oversized percent similar to an amount of shrinkage experienced by that ceramic material upon firing into a final hardened state. The machined compressed powder billet forms a pre-firing guide block which is fired at sufficient temperature and for sufficient duration so that it achieves its final hardened state as a ceramic guide block having dimensions precisely matching those of a prior non-ceramic guide block being replaced. The ceramic guide block can then be substituted into the saw for use in supporting the saw blade. | ||||||||||||||||||
